In passing, yes, but my recommendation is that we update the curriculum with a more "how things work" approach and include new topics (many of them technological) for math credit.
Many students in economically disadvantaged zip codes demonstrate a hunger for this knowledge.
South Africa seems to be moving in this direction: if you're from a township, you want access to a tuXlab. Or maybe that trend is over too -- I haven't visited the RSA in awhile.

You are not disagreeing then, only underlining your distopian view of the present and suggesting in some past golden age, of which you wax nostalgic, injecting SQL would have seemed logical.
You're right, it'd be anachronistic to imagine teaching SQL in the 1960s.

Sorry, I was a bit out of date.
I remember when WC3 was promising we'd have SQL on the client side in the browser, but the spec writers have abandoned this effort in favor of a different API.
I'd say rather that the graphic arts are indeed "mathy".
You need coordinate systems, splines, sprites, Bezier curves... Turtle Art, fractals.
Saying graphic arts is not mathy is like saying M.C. Escher is not mathy. Or Penrose tiles. Or polyhedrons.

You seem to agree that my curriculum reform proposals make sense, just we don't happen to live in a civilization that's capable of upgrading so drastically.
You're like Jared Diamond in 'Collapse: How Societies Choose to Fail or Succeed', explaining why it won't happen.
